So your only going to increase your Test for 4 weeks? It takes 2 weeks to fully kick in, I wouldn't increase the test if your only going to increase it for 4 weeks, that's a waste and your only going to trigger side effects. Unless your going to keep the levels high for at least 8 weeks don't even bother, any progress you make in that time will go back to normal as soon as you drop back down to 100mg unless you stay on for longer. 4 weeks isn't long enough for permanent change.
